I would like to listen to Spotify Premium that I play from my Macbook or Ipad over my 40PFL9704 (for it's speakers). But I somehow can't make the tv connect with my Macbook Pro. They are using the same wireless network and are both using this.

Do I need some sort of software on my Macbook in order for the tv to recognize me? Please help because I have not ot a clue..
